A concave mirror forms a real, inverted image of an object placed beyond its center of curvature. Where will the image be formed?
A concave mirror forms an image that is twice the size of the object. If the object is placed 15 cm from the mirror, where is the image formed?
A convex mirror has a focal length of 15 cm. What is its radius of curvature?
A dentist uses a mirror to see a magnified image of a tooth. Which type of mirror is being used?
A person stands 2 m in front of a plane mirror. What is the distance between the person and his image?
A student places an object 10 cm in front of a convex mirror with a focal length of 20 cm. Calculate the image distance (v).
Explain why a concave mirror can be used to focus sunlight to a point.
If an object is placed at infinity in front of a concave mirror, where is the image formed?
If an object is placed at the center of curvature of a concave mirror, what are the characteristics of the image formed?
If an object is placed at the focus of a concave mirror, where will the image be formed?
If the focal length of a mirror is negative, what type of mirror is it?
If the magnification produced by a mirror is -2, what does the negative sign indicate?
If the object distance (u) is -30 cm and the focal length (f) of a concave mirror is -10 cm, calculate the image distance (v).
If the radius of curvature of a concave mirror is 20 cm, what is its focal length?
What is the focal length of a plane mirror?
What is the mirror formula relating object distance (u), image distance (v), and focal length (f)?
